Getting professor level A/A+ early on is great for maxing out your students, but it makes it a hell of a lot more tedious to keep everyone's motivation up! Normally if you can only instruct 3-4 students at a time you'd have enough motivation for the month, but I need to do the dining hall meals almost every free day just to keep everyone up! Food was really running out for me by the end. (I didn't realize you could plant veggies until like chapter 21 NG+ since I was just abusing the flowers that give you speed carrots) Because of this I just split up all my monastery time throughout the month instead of doing everything in one go, made it less tedious.
I definitely regret not making Felix a dancer. He would have gotten magic like he already does as a Mortal Servant, but that 20+ avoid with swords would have been really juicy.
Ingrid is probably my best Fire Emblem character ever. Best resistance, speed and Dex in the game, top tier strength, very good defense, and unfathomable avoid. Very rarely will anyone have over a 40% of touching her. Plus she flies.
I'm on the last chapter of Blue Lions now. Dreading it a bit since the last chapter of Black Eagles took me 4 hours to work through
Also, if anyone does the online liaison stuff, pretty safe bet to send out your character with a master seal. It's something everyone can use, so you'll be ranking in a lot of cash. I sent out a character for a few days and they came back with 62 000 gold.
